## Abstract

A method for making a female member of a hook-and-loop fastener includes the steps of: (a) bonding together a base layer and a surface layer, that is formed from a fiber material and that is superimposed on the base layer, by applying heat to the surface layer so that fibers of the surface layer are curled; and (b) immediately after step (a), subjecting the surface layer to a rapid cooling treatment so as to set the curled fibers of the surface layer.

## Claims

### Claim 1

A method for making a female member of a hook-and-loop fastener, comprising the steps of:
(a) bonding together a base layer and a surface layer, that is formed from a fiber material and that is superimposed on the base layer, by applying heat to the surface layer so that fibers of the surface layer are curled; and
(b) immediately after step (a), subjecting the surface layer to a rapid cooling treatment so as to set the curled fibers of the surface layer.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the base layer is made of a material selected from the group consisting of a complex spunbond nonwoven, a complex staple nonwoven, a paper-fiber-containing nonwoven, and a plastic film.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the surface layer is made of a material selected from the group consisting of an unbound complex fiber web, an air-through nonwoven, a thermal bonding nonwoven, a spunlaced nonwoven, and a jacquard spunlaced nonwoven.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the surface layer is made of a material selected from the group consisting of an unbound complex fiber web, an air-through nonwoven, a thermal bonding nonwoven, a spunlaced nonwoven, and a jacquard spunlaced nonwoven.

### Claim 5 (depends on 1)

The method according to claim 1, wherein step (a) is conducted by passing the base layer and the surface layer through a hot-pressing roll device.

### Claim 6 (depends on 1)

The method according to claim 1, wherein step (b) is conducted by blowing cooling air toward the surface layer.

### Claim 7 (depends on 1)

The method according to claim 1, wherein step (b) is conducted by passing the surface layer through a cooling roll device.

### Claim 8 (depends on 1)

The method according to claim 1, wherein step (b) is conducted at a work temperature ranging from 0° C. to 30° C.

### Claim 9 (depends on 1)

The method according to claim 1, wherein step (a) is conducted by heat-laminating the base layer to the surface layer.

### Claim 10 (depends on 9)

The method according to claim 9, wherein the surface layer is made of a material selected from the group consisting of an unbound complex fiber web, an air-through nonwoven, a thermal bonding nonwoven, a spunlaced nonwoven, and a jacquard spunlaced nonwoven.

### Claim 11 (depends on 10)

The method according to claim 10, wherein the base layer is made of a plastic film.
